Terminals can be seen redrawing .. from the physical screen top to the physical screen bottom, very slowly. This rendeing order is different from the logical orientation of the large virtual screen. From what I've seen in one of your other bug reports, you seem to be running Debian's 2.6.30 kernel without the firmware-linux package. Please install firmware-linux since it is necessary for hardware acceleration on some boards and I guess it may help for rotation.

I have tested this only after installing the firmware because DRI would not work otherwise. You can see in the log that in this case DRI GLX was started without problems.

When the screen is not rotated the performance is the same on both screes. This is not an issue of framebuffer size limits - it must be larger when the screen is not rotated. Please stop reporting hundreds on bug against the old 6.9.0 radeon driver. You should work on debugging 6.12.2 instead, for instance by testing a recent git snapshot and by raising your 6.12.2 problem to the upstream bugzilla. thanks, Brice -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of unsubscribe.
